What if Yasuo's windwall didn't block projectiles from behind it?

yasuo has some great outplay moments when playing on his windwall id rather see his passive crit changed so that he doesn't hit all game power spike from 2 completed items

Windwall is an abdurd ability in combination with yasuos kit and playstyle. its the kind of ability that belongs on a support, not a bursty fighter/adc. I'm not really sure how you balance windwall without moving it to an entirely new champion. Late game he can cast a 4 second duration windwall every 10 seconds. therefore as a projectile based champion like velkoz, 2/5 of the time you have no auto attack or ranged abilities. essentially windwall makes you useless for longer than it takes him to kill you. its a cool concept but utterly broken mechanic in light of yasuos dash and skillshot
